Your paperwork, read, filed and added up.

Email it, send it on WhatsApp, or drag it in. A 204-page claim bundle comes back as four documents, each one read and filed in your Drive. Every figure lands in a spreadsheet nobody typed. Open it in Excel, or ask CernaFlow what it adds up to.

An illustration of CernaFlow at work. A 204-page claim bundle arrives by email, a photo of a receipt by WhatsApp, and an invoice is dragged in. Every page of the bundle is read, and it is cut at pages 5, 18 and 59 into a claim form, a police report, a loss schedule and repair estimates. The photo is identified as a receipt and the upload as an invoice. The receipt is read: ALDI, 11 June 2022, a total of 88.97 and 30 line items. Each document is filed as a PDF in a Google Drive folder named after its type. Then someone asks how far the repair estimates are over the loss schedule, and the answer comes back with a chart by room: 38,420 against 35,180, 9.2% over, and 2,750 of the gap is the kitchen.

No pipeline to build. Nothing to install, nothing to deploy, nothing to route. Turn on the channel your team already uses and the next thing that arrives goes through it.

Any document. The fields you asked for.

A crumpled receipt, a stamped invoice, a bill of lading, an agreement, a medical summary, a payslip. Each one is read into its own template. Start from one of 34 ready-made templates, or write your own.

One bundle in. Each document its own file.

A 204-page PDF is rarely one document. Every page is read to find where one ends and the next begins, each piece is matched against the documents you care about, and the parts come out filed separately. Nobody sits and splits the scan.

1.0Split

A three-invoice PDF open in CernaFlow. In the list, the bundle carries a Split tag and 3/3, with its three invoices indented beneath it. The first invoice is open: the scanned sales invoice on the left, and beside it the fields read from it, including invoice number BZV00107769, date 2026-01-14, a total of 10556 and line items such as Pomme d'amour, 10 at 80. Names and tax numbers are blurred.

1.1One file in, three documents out

1.2Each keeps its own pages

1.3Read into the fields you chose

1.4Every line item, priced

Filed and keyed in, with nobody doing either.

Each document is filed as a PDF in your Google Drive or SharePoint, in a folder named for what it is. Nobody sorts the shared drive again. Beside the folders, one spreadsheet per template gains new rows every hour, with your field names across the top. Pivot it, reconcile it, or point your reporting tool at it. Or download any selection as a CSV.

Ask across all of it at once.

Once documents are in, anyone on the team can ask a question across all of them. It searches what has been pulled out, does the arithmetic, and draws a chart when a chart is the answer.

Invite everyone. You pay for pages, not people.

A page is one page of a PDF, or one photo. There is no seat count, so the auditor who signs in twice a year costs nothing.
